Embodiment 1
A kind of doctor blade device of realizing high cleaning efficiency and low roll surface damage simultaneously comprises doctor blade, the blade drive rotaining device 4 that is installed on roll surface one side to be cleaned and is used for driving the rotating mechanism that blade drive rotaining device 4 rotates.Above roll surface 8 and doctor blade 3, RF transmitter is installed, corresponding with it, below roll surface 8 and doctor blade 3 infrared receiver is installed, the current signal that produces according to infrared receiver tube 2 is judged the size in gap between roll surface 8 and the doctor blade 3.
5 rotating mechanisms: it rotates by cylinder and carries out, and drives blade drive rotaining device 4 and rotates also final location of realizing doctor blade 3.On rotating mechanism 5, rotating mechanism angle position-limit mechanism 6 is set, be used for the anglec of rotation of restriction rotating mechanism 5.Described blade drive rotaining device 4 is divided into two parts up and down, carries out clamping by 7 pairs of doctor blades of clamping screw 3.Blade drive rotaining device 4 bodies are arranged on the rotating mechanism 5, and when rotating mechanism 5 rotations, it drives doctor blade 3 and rotates together.
Use: when doctor blade is installed, open RF transmitter and infrared receiver tube system, and make doctor blade slowly close to roll surface by regulating rotating mechanism.Under the situation that doctor blade is not rotated in place, because infrared ray can be by the gap transmission between blade and roll surface, so can see the correlated response behind the receiving infrared-ray on the infrared receiver tube, the prompting blade is not regulated and is put in place, when doctor blade during near the roll surface final position, it is more and more fainter until final disappearance that the infrared ray of infrared receiver tube receives reaction, illustrates that scraper adjusts to the right place this moment, clamping screw can be locked.Behind above step location, blade just contacts with roll surface and does not have big friction in the time of can realizing rotating to this position, can realize the high-efficiency cleaning of roll surface, can realize the low-loss of roll surface and scraper again.
1, in the blade installation process, opposite side does not have infrared ray reception signal as if finding one-sided infrared receiver tube signal obviously, and the one-sided installation inclination of blade is described, needs adjustment blade position in time at this moment, to guarantee cleaning effect.In the blade installation process, all disappear if both sides infrared receiver tube signal takes place, and mid portion position infrared ray receives the tangible situation of signal, illustrate that the blade relevant position exists damage or distortion, need in time to adjust blade this moment, to guarantee not take place the roll surface damage.More than these two kinds of situations all be what under the situation of traditional manual detection, be difficult to realize.
2, along with the use of scraper, may there be all kinds of situations such as overall wear, one-sided wearing and tearing, centre position wearing and tearing, the situation that can utilize the infrared emission system dynamically to follow the tracks of scraper and roll surface this moment, and in good time adjustment doctor position or replacing scraper are to realize best cleaning effect.And traditional scraper use pattern is in that to use the later stage to continue to increase the cleaning effect that its working pressure causes with the compensation blade wears not good, but because pressure strengthens, again doctor blade and roll surface are caused bigger wearing and tearing, dynamically follow the tracks of scraper and roll surface gap situation and the in good time doctor position of adjusting with native system and compare, there is very big problem in conventional method.
Use the artificial judgment installation accuracy and rely on scraper pressure to remove the roll surface adhesive different with traditional scraper, the dynamic tracking of scraper and roll surface position in accurate location when the new scraper of this kind can be realized installing and the use, owing to install gap minimum (relying on infrared ray emission and receiving system to realize) between back roll surface and the scraper edge of a knife, so can realize high cleaning efficiency.Simultaneously, owing to be not to carry out roll surface cleaning by exerting pressure, so the damage of roll surface and doctor blade is all obviously reduced, can significantly improve both service life.
In addition, in the installation process, if the one-sided situation not in place of doctor blade takes place, the respective side infrared receiver tube will receive infrared ray that RF transmitter is launched, and give operator's respective reaction information, so the operator can adjust doctor blade to the right place according to the infrared signal reception condition.
Again, in installation process, if blade both sides infrared receiver tube does not all have the reception signal, but the central sections infrared receiver tube has the reception signal, it is crooked or damaged to illustrate that then scraper or roll surface exist, and this moment, the operator can determine whether to change doctor blade or roller according to actual conditions.
In use, the operator can dynamically follow the tracks of the gap of roll surface and scraper, if the situation of scraper overall wear takes place, then on dutyly can adjust doctor position or more renew doctor blade according to actual conditions.
In use, the operator can dynamically follow the tracks of the gap of roll surface and scraper, if the situation of the one-sided wearing and tearing of scraper takes place, then on dutyly can adjust doctor position or more renew doctor blade according to actual conditions.
Rotating mechanism can rotate within rotary stopper defined scope, and shown in figure, its spacing position of left is vertical with the roll surface tangent line, and its most right-hand spacing position is parallel with the roll surface tangent line, and the rotating mechanism rotating range is 90 °
The utility model positions and carries out according to this installation and dynamic adjustment of doctor blade to scraper and roll surface position by the signal feedback system that has RF transmitter and infrared receiver tube.All obviously minimizings of damage that this kind removed the roll surface adhesive with minimum gap by accurate location method and traditional pressure removal method compare roll surface and doctor blade.Simultaneously owing to carried out accurate location and installation, also can get a promotion to the effect of roll surface cleaning.Because but adjustment is dynamically followed the tracks of in blade and roll surface gap, can realize the omnidistance high-efficiency cleaning in the whole life cycle of blade.
The utility model is simple in structure, and is with low cost, can effectively improve cleaning efficiency and reduce roll surface and the scraper loss, realizes the prolongation of roller and scraper life cycle, reduces and changes number of times, enhances productivity.
